I use over the ear protection. I can hear normally with them if I choose to, and they deaden noises over 85 decibels. They hear in mono, unlike the ear defenders which cost about 40 dollars more, but with that broad of a price difference, I like my Harbor Freight clone just fine, they were under 15.00 and I use them all the time; dishes, vacuuming, driving with the windows down, and fireworks.
